Purpose/edited by ferrous chloride

Ferrous chloride have unique decolorizing ability, suitable for dyes, dye intermediates, printing, dyeing, wastewater treatment in papermaking industry. Can simplify water treatment technology, shortening the period of water treatment, reduce water treatment cost. For all kinds of wastewater, electroplating, leather, paper making wastewater has obvious treatment effect, for all kinds of heavy metal ions in waste water, sewage removal rate of close to 100%; Processing cost is low, is ideal wastewater treatment drugs. Directly used for sewage and waste water treatment, as reductant and mordant, widely used in fabric printing and dyeing, pigment printing and dyeing, manufacturing industries, also used in superhigh pressure lubricating oil components, also used in medicine, metallurgy and camera. In addition to the following purposes:

1, the production of iron trichloride:

With solid ferrous chloride, hydrochloric acid and chlorine gas as the main raw material to produce ferric trichloride, the first is the ratio of ferrous chloride solution, heating ventilation with chlorine, ferric chloride solution can be obtained, if the ferric chloride solution by filtration, heating, chlorine, nitric acid oxidation or concentration, cooling, can get solid ferric chloride hexahydrate. The ferric chloride into ferric trichloride completely reaction. Product quality in line with national standards GB1621-79 indicators.

2, the production of solid polymer ferric chloride:

(1) into ferrous chloride crystals in the reaction kettle, add water after slow when heated to 45-65 ℃, to start the reaction kettle mixer, and through compressed air at the bottom of the reaction kettle, stops heating temperature to 85-85 ℃;

(2) in reaction kettle upside in alkaline aqueous solution reaction, reaction and hydrochloric acid aqueous solution under the reactant liquid level and temperature control in 90 ~ 95 ℃, to detect the reactants in the Fe write [2 +] 0.15% or less is to join the lye, on the base of up to 5 ~ 10% stop to join the hydrochloric acid aqueous solution, stirring, access to press the material hot compressed air into the machine cooling into solid, after smashing become a high content of solid polymer ferric chloride, application of the present invention production of solid polymer ferric chloride, stable quality, low cost, no three wastes produced products have good stability, production process, product without secondary pollution.

3, the production of polyaluminium chloride iron flocculant (PAFC) :

Using aluminum salt and iron salt flocculant production on the basis of a kind of inorganic polymer flocculant.

4, with ferrous chloride liquid quality printing and dyeing wastewater treatment methods:

Use the method of ferrous chloride treatment of printing and dyeing wastewater with high quality. By adding the polarity in the printing and dyeing wastewater after medium and change the degree of ionization, with FeCl2. Processing after the printing and dyeing wastewater treatment fluid also with 1 to 2 times the amount of untreated printing and dyeing wastewater is mixed, then adjust pH neutralization, coagulation sedimentation, after the solid-liquid separation emissions, waste water COD removal rate of 50% or more, removal rate of chroma 70 ~ 90%, the water is not rosy, save wastewater treatment costs by about 30%. FeCl2 create conditions are widely used in printing and dyeing wastewater treatment, can produce good economic and environmental benefits.

For all kinds of wastewater, electroplating, leather wastewater has obvious treatment effect, for all kinds of heavy metal ions in waste water, sewage removal rate of close to 100%; Unique decolorizing ability, suitable for dyes, dye intermediates and wastewater treatment of printing and dyeing industry. Can simplify water treatment technology, shortening the period of water treatment, reduce water treatment cost.

5, production erasable ink:

Is adding inorganic salt mixture of dye, the formula for sodium polyacrylate, ferrous chloride, cobalt sulfate, sodium sulfate, color dye and water, and said the color dye can be black, blue, green, red pigment, etc. This kind of ink to write words with common eraser is easy to wipe away, after the handwriting, not easy to change color, but also long-term preservation.

6, silt sand soil slopes fast curing agent:

Ferrous chloride + calcium hydroxide, with larger compressive degree: 40-50 kpa (28 days) 4-5 times.

7, ferrous chloride additives, fine water mist fire extinguishing agent:

In order to improve the conventional water mist fire extinguishing effectiveness, expand the scope of its application, this article adopts the method of small scale experiment, to study the water mist containing ferrous chloride additives in different fuel types, additive concentration, the effectiveness of extinguishing pool fire under pressure. The experimental results show that: ferrous chloride is added to water mist, significantly affect its extinguishing performance; Water mist fire extinguishing time as to join the quality of ferrous chloride concentration change and change, and there is a minimum concentration of extinguishing time; Water mist nozzle pressure and fuel types also have an impact on water mist fire extinguishing performance, nozzle pressure, the greater the shorter average water mist fire extinguishing time; Under the same experimental conditions, water mist shorter time to destroy the kerosene fire ethanol fire time.
